Will These Pulley Kits Clear the Cross Member on a C2 or C3 Corvette?
These kits normally clear the cross member on otherwise stock 1965 - 1982 C2 and C3 Corvettes.
That being said, issues such as age, condition, manufacturer, etc. of motor mounts can cause clearance problems. Fortunately, most clearance issues can be solved by putting a spacer between the engine and the motor mount. This was a factory solution for GM on 1966-74 big block Corvettes with air conditioning. The factory style spacers are reproduced and are available from various Corvette suppliers listed below. They are specified for big block, but they will fit Chevy small block engines as well.
1963 - 1964 engines will most likely have to be shimmed upward for the crank pulley to clear the cross member. Make sure you have enough hood clearance!

Additional Notes
- Most Chevy blocks have drilled and tapped holes on either side of the harmonic damper, but a very few do not. All of our SB Chevy kits require these holes
- Our kits will not work with engines mounted with front motor mounts. Side motor mounts are recommended
Additional Notes - Driver Series
- Driver Series Kits will work with all heads including those without accessory bolt holes
- Driver Series Kits are one belt serpentine systems with a spring loaded OEM tensioner
- Driver Series Kits are designed for use with electric cooling fans. If you need to run a mechanical fan, contact us and we can make modifications to the waterpump pulley. Also, this kit uses a reverse rotation waterpump, so make sure the fan is a reverse rotation fan.
